NONLINEAL CROSSARM FOR BRACKETING ELECTRICAL DEVICESBACKGROUND OF THE INVENTION This invention relates generally to meansfor mounting electrical devices to a utility pole, and more particularlyto a nonlineal or arcuate crossarm that is useful for bracketingelectrical devices away from the utility pole, but yet arranged withinconvenient reach of a utility man working upon said pole.

Many apparatuses have been devised for stably supporting electricaldevices upon a utility pole. Oftentimes, as in the past, the crossarmused for this purpose was generally a straight piece of lumber or thelike which simply attached at its midpoint to the utility pole, withvarious electrical devices being mounted upon its lateral extensions,this type of a prior art device being by way of example disclosed in myprevious U.S. Pat. No. 3,468,57 1. Other prior art devices, such as thecapacitor assembly as disclosed in U.S. Pat. No. 3,254,270,

recognized that some convenience was achieved through the use of a framestructure having angularly extending end portions, but this capacitormountingdevice did not include the use of brackets that may alternatelymount other types of electrical equipment such as arresters, pothead's,or the like, at various angular relationships to the vertical. In myprevious U.S. Pat. No. 3,497,171, it was disclosed that variousmultiwinged fixtures may be utilized for attaching electrical devices ofthe aforementioned category to a utility pole, but this device did notincorporate the convenience and ease of mounting of the arcuatecrossarm, and its various brackets, as disclosed in this invention, butrather, was more concerned with the disposition of the electricaldevices at various radially disposed distances surrounding the utilitypole.

It is the principal object of this invention to provide an arcuatecrossarm that partially surrounds the utility pole but yet displaceselectrical devices a sufficient distance from said pole through the useof various brackets which include mounting surfaces that may be arrangedvertically or at an angle with respect to the vertical.

It is another object of this invention to provide a nonlineal crossarmincluding multiple brackets that are useful for mounting a plurality orcluster of hook-stick switches, potheads, arresters, or relatedelectrical devices upon a utility ole. p It is a further object of thisinvention to provide an arcuate crossarm being a unitary structure thatis useful for mounting a plurality of heavy duty, three-phase electricalequipment upon the utility pole.

Another object of this invention is to provide a bracket for verticallymounting electrical devices upon an arcuate crossarm, which bracket maybe easily inverted by a worker, even while ascended upon the utilitypole, so as to provide for a forward inclination and convenientdisposition in the mounting of one or more electrical devices upon saidutility pole.

An additional object is to provide an adjustable bracket which may bedirectly anchored to a utility pole.

It is still another object of this invention to furnish a unitaryarcuate crossarm disposed for connecting with spatially arrangedbrackets formed from either angles, multi-flanged angles or tee angles,that may conveniently support electrical devices either directly orthrough the use of various pads or hangers.

Other objects will become more apparent to those skilled in the art inthe light of the following description and accompanying drawings.

SUMMARY OF THE INVENTION This invention incorporates the use of anangled crossarm, preferably being arcuate, partially encircling theutility pole, which crossarm is anchored proximate its midpoint foraesthetic and/or balancing purposes directly to the utility pole. Tofurther stabilize the mounting of the crossarm upon the utility pole, apair of trusses extend from the pole to approximately the quarter pointsof said crossarm, so that the mounting of heavy duty equipment such asarresters or disconnect switches to a bracket at one end of the crossarmwill yet be stably supported upon the utility pole.

The connecting of this arcuate crossarm to the utility pole isbeneficial from the standpoint of leaving the backside of said polesubstantially vacant, so that the utility man working upon the pole willhave sufficient clearance for movement, but yet due to the arcuatenessof the crossarms, and particularly locating the electrical devices alonga curve almost laterally of the utility pole, the workmen will yet beable to have sufi'icient reach for installation or manipulation ofelectrical devices mounted all along the crossarm to its variousbrackets. As previously stated, other mounting devices eitherincorporate just a straight crossarm, which makes it difficult for autility man to have access to the electrical devices mounted especiallyat its ends, or the crossarms are bent or disposed almost entirelyaround the utility pole, which does not leave sufficient clearance forthe utility man to maneuver along the backside of the pole, whileplacing the electrical devices mounting to the front of the crossarm ata distance beyond his reach due to his confinement.

The various brackets incorporated and used in combination with thisarcuate crossarm all provide a mounting surface of a variety of sizes soas to accommodate a particular sized electrical device, such as a smallarrester, or a heavy duty threephase arrester, cutout or hook-stickswitch of the type used with three-phase equipment and being of eitherthe intermediate or distribution type. Obviously, the latter typeequipment can be manufactured of substantial size, having somesignificant weight, and therefore, the configuration of the bracketsutilized in combination with the arcuate crossarm must be structurallysound so as to support the heavier devicesstably upon the utility pole,free from any damage that might otherwise occur during adverse weatherconditions.

Generally the brackets of this invention include a mounting surfacehaving inturned ends which connect upon a support means that securesdirectly to the crossarm. The downward inturned edge of the mountingsurface is braced either to the opposite end of the support means, or itmay be braced directly to the anchor means as is the case with thebracket connecting proximate the midpoint of said crossarm. Whenmanufactured in this manner, the mounting surface may be constructed sothat when properly secured its surface will be vertically arranged, butwhen inverted, the connection of its various inturned edges will providefor an inclination in said mounting surface. Under certain conditions itis desirable that various electrical devices such as potheads,arresters, or hook-stick switches have some inclination angled away fromboth the utility pole and its crossarm for purposes of clearance andeasier wiring of the connecting electrical lines, to provide properspacing between a cluster of such devices, or more particularly withregard to disconnect switches, to permit easy opening and closing ofsuch a switch by a lineman. Hence, the spatial attachment of thesebrackets to an arcuate crossarm is such that each bracket may providesupport for a cluster of electrical devices, which are convenientlydisplaced away from the utility pole, but yet are each within convenientreach of the utility man who has located himself to the backside of thepole for purposes of working upon or exchanging particular of theseelectrical devices.

When it is desired to provide a less clustered attachment of variouselectrical devices to the arcuate crossarm, a pad, having someangularity to it if desired, make connect directly to the support meansin place of the usual mounting surface as previously described, and saidpad is conveniently bifurcated so as to provide for attachment of, forexample, a flange style pothead to each bracket. Furthermore, variouscombinations of structural angles, such as multi-flanged angles or teeangles, may be connected spatially upon the arcuate crossarm, providingconvenient mounting surfaces that may support hangers or the like formounting of other type electrical devices such as cutout-arrester units.Obviously, a combination of various electrical devices may be used upona utility pole, and cooperate with each other, to achieve a particularresult. Thus, the combination of angles, or structural tees, as hereindefined, when formed into a bracket, are conveniently disposed forproviding a mounting of particular electrical devices in combination toproduce a single function. Hence, a series of three intermediatearresters and three disconnect switches may be mounted upon the variousbrackets defined herein, with the disconnect switches being mounted tothe inclined mounting surface of the brackets, and the arrester beingmounted upon each support means to provide a paired group of devices toachieve a particular electrical function. The various angles, orstructural tees, may be spatially connected upon the arcuate crossarm,with their flanges being either longitudinally extended in alignmentwith the curve of the crossarm, or even project vertically to provide amounting surface for connection of one or more electrical devices, aspreviously described. The flanges of the structural tees may be arrangedin abutting relationship upon the crossarm so as to provide a fulllength of mounting surface for connection of, for example, the base of aheavy duty hanger which may be useful for supporting a cutout ofsignificant size.

This arrangement of various brackets as used upon this arcuate crossarm,and the usefulness of its various combination of brackets that may beformed from various structural angles or tees will become more clearwhen reviewing the preferred embodiments.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings,in FIG. 1, reference characteristic A generally depicts one embodimentof this electrical equipment mount, with reference numeral 1 indicatinga nonlineal crossarm, being arcuate as herein shown, which partiallyencircles the utility pole P, and connects with the same through theagency of an anchor means 2, with a pair of trusses 3 and 4 furtherstabilizing this support. A series of brackets 5, 6 and 7 connect toapproximately either end and at the midpoint of said arcuate crossarm,and are disposed for holding a variety of electrical devices (not shown)properly displaced away from the pole, but yet within easy reach of theutility man who may be working upon said pole.

By referring to FIGS. 2 through 4, it can be seen that the arcuatecrossarm 1 may be composed of any form of structural material, butpreferably is formed of an extruded aluminum alloy, and being of thetube, channel or box channel design in crosssection. As here shown, thetrusses 3 and 4 connect at approximately the quarter points of saidarcuate crossarm, being fastened thereto by means of the series offasteners 8 and 9, with the other ends of said trusses being connectedapproximate the sides of said pole. In this manner, it can be readilyseen, especially in FIG. 2, that there is available clearance along theback side of the utility pole for maneuvering of the utility worker,giving him approximately climbing space, but at the same time, due tothe arcuateness of the crossarm, the braces and mounted electricaldevices will be within easy reach for handling by said worker.

The anchor means 2 of this invention comprises a substantiallyrectangular shaped structure that includes an vend member 10 which isdisposed for fastening directly to the side of the crossarm by means ofa series of fasteners 11, with a pair of integral legs 12 extendingrearwardly therefrom, with each terminating in a substantially C-shapedfoot 13 thatis disposed for mating engagement with the distal ends 14 ofthe rib members 15 that are integrally formed with the curved spine 16,that anchors to the utility pole. A series of properly placed thru-boltson the pole will accomplish this anchoring. A crossbrace 17, held by thefasteners 18, further stabilizes the structure of this anchor means. Asshown, a pair of grounding lugs 19, each being secured to a leg 12 areconveniently disposed for providing grounding of the crossarm andelectrical devices if necessary.

The end brackets 5 and 7 of this invention are substantially identicalin construction, with each bracket including a support means 20, hereinshown as a length of structural angle, with the upward portion of amounting surface 21' being fastened to one end of said support means,while the bottom portion of said mounting surface connects with a brace22 that is fastened to the other end of said support means. It is to benoted that the edges 23 and 24 of both the upward and lower portionsrespectively of each mounting surface 21 are inwardly or inturned bentso that they may be each disposed in overlying relationship with respectto the parts to which they attach, here being the ends of the supportmeans 20 and the brace 22. Likewise, the ends of each brace areaccordingly bent to that angle which provides for their snug and flushmounting with the parts to which they connect, here being the back endof the support means, and the inwardly bent edge 24 of the downwardportion of each mounting surface. It is to be noted that the verticallydisposed flange 25 of each support means or angle 20 is formed havinginclined edges at each of their lateral ends 26 and 27, so as to provideclearance for the attachment of both the mounting surface 21 and brace22 of each bracket thereto.

The bracket 6 that connects approximately to the midpoint of the arcuatecrossarm is structurally formed somewhat similar to the brackets 5 and7, wherein this bracket includes a mounting surface 28 having aninwardly or inturned bent edge 29 in its upward portion being fastenedto a support means or plate 30, which plate secures by means of a seriesof fasteners 31 to the upper edge of said arcuate crossarm. A pair ofsupplemental fasteners 32, see FIG. 2, are structurally secured to theplate 30, and provide further support for attachment of additionalelectrical devices, such as arresters, or the like. This allows for theconvenient clustering of electrical devices around each bracket. Thedownward portion of the mounting surface 28 is formed having an inwardlyor inturned bent edge 33 which secures by means of a fastener as shownto a brace 34, which brace at its back end connects by means of afastener as shown to the crossbrace 17 that is structurally securedwithin the anchor means 2. Thus, the mounting surface 28 is structurallysupported within this electrical equipment mount, and is useful forsupporting electrical devices of sufficient weight. It is also likelythat a single bracket 6 may be anchored to a pole by having its plate 30connecting to the anchor means or be retained thereto by means of anangle or the like.

Each of the mounting surfaces 21 and 28 of the various brackets areherein shown to be relatively flat, and vertically disposed, and throughtheir series of fasteners or attaching areas 35, they readily supportthe various electrical devices such as hook-stick switches, potheads,fuse cutouts, or the like. In addition, various other supplementalbrackets, as at 36, or supplemental fasteners, as at 37, are providedthroughout the mount to allow for convenient clustering of electricaldevices.

Upon viewing FIG. 5, it can be seen that each bracket of this invention,as previously described, can be manipulated so that its mounting surfacemay be disposed at an angle with respect to the vertical. This isachieved through an inverting of a mounting surface as previouslydescribed and as shown at 38, so that the inturned edge of its normallydownward portion, now at 39, which is bent at an acute angle, is nowdisposed and becomes the upward portion of the mounting surface, andsecures to one end of the support means 40, while the inturned edge ofthe normally upward portion, as at 41, of said mounting surface nowbecomes the downward portion and connects with one end of the brace 42.As previously disclosed, the

other end of the brace 42 attaches directly to the opposite end of thesupport means or angle 40. Hence, under this manipulation, the mountingsurface of each bracket may be angularly disposed, which in this case isarranged at approximately a angle with the vertical, so that variouselectrical devices, such as a disconnect switch, may be mounted theretoand disposed at that angle which permits its easy handling, such as inopening or closing ofthe switch by a lineman.

F I65. 6 and 6A disclose the arcuate crossarm l which is secured to theutility pole by means of an anchor means 2, but which incorporates avariation in the form of brackets utilized at approximately each end'andat the midpoint of said crossarm. The end connecting brackets 43 aresimilar to the support means previously described and used inconjunction with the brackets 5 and 7, and comprise a length of angle,each connecting approximately at its center to the end of the crossarm.When disposed in this manner, either the horizontally disposed flange44, or the vertically disposed flange 45, of each bracket provide amounting surface to which electrical devices may connect, as through themedium of the fasteners, as for example shown at 46. The centralconnecting bracket 47 connects approximately at the midpoint of thefront portion of the crossarm. This bracket also comprises an angularmember, being more specifically described as a multi-flanged angle,which has a pair of upper and lower spaced apart flanges 48 and 49connecting with the crossarm, with another of its flanges, as at 50,projecting outwardly and which may support electrical devices throughthe agency of fasteners, such as at '5]. Obviously other fasteners mayattach to the bracket to support electrical devices. The web portion 520f the tee is maintained flush with the outer edge of the crossarm tofurther stabilize the mounting of any electrical devices upon thisbracket.

By referring to FIGS. 6B through 6D, there is disclosed a pad 53 whichmay be mounted upon the horizontally disposed flanges of the brackets 43and 47, by connection of the various fasteners, as at 54, through itsapertures 55. This pad includes a flat portion 56 for attachment to theflanges, as aforesaid, and also has an integrally and angularly bentportion 57, which is bifurcated as at 58, so as to be readily adaptablefor mounting, for example, flange style potheads. This pad desirably isformed for extra rigidity so as to readily support the mounting of heavyduty electrical devices thereto and upon the crossarm.

FIGS. 7 and 7A disclose a further modification in the brackets utilizedin conjunction with the arcuate crossarm l, as anchored to the utilitypole, and these brackets also connect proximate the ends and to themidpoint of said crossarm. Each of the end connecting brackets 59, andalso the central connecting bracket 60, are similar in configuration tothe bracket 47 previously described. These angles have multiple flanges,with the overlying flanges 61 and 62 of each bracket attaching to thecrossarm, with the web portions 63 extending downwardly for flushmounting against the proximate edge and ends of the crossarm. Each ofthe end attaching brackets 59 have a flange 64 that projects outwardlyin a similar longitudinal alignment approximating the curve of thecrossarm. Each flange 64 is provided with a fastener 65 which is usefulfor retaining one or more electrical devices. The bracket 60 securingapproximately at the midpoint of the crossarm 1 also has a flange 66that projects outwardly for mounting of an electrical device thereupon.

FIGS. 8 and 8A show a further modification in the form of bracketsutilized in conjunction with the crossarm 1 as anchored to a utilitypole. Each of these brackets 67 also connect approximately to the endsand at the midpoint of the crossarm, and each comprises a pair of anglemembers 68 and 69, formed as structural tees, whose web portions 70 aresecured by means of fasteners, as at 71, to the upper and lower edges ofsaid crossarm, while one flange 72 of each tee projects wither upwardlyor downwardly and having surfaces for mounting of electrical devices bymeans of the fasteners 73 as shown, while the other flanges 74 aredisposed in abutting relationship mounted flush over the ends or frontedge of said crossarm.

FIG. 8B discloses a form of hanger 75 which includes a base 76 whichmounts to the type of brackets 67 disclosed in F IG. 8A, with said baseincluding a shank 77 that extends angularly therefrom and includes aclamp 78 upon its opposite end to which an electrical device, such asthe cutout C as shown, may attach. An arrester T, of thiscutout-arrester unit, may be clamped to the upper edge of flange 72, tocomplete this cluster of electrical devices. By providing for an angulardisposition of a cutout in this manner, a utility man may easilymanipulate the cutout as desired, since its angularity and dispositionmakes it readily and openly exposed for handling. Furthermore, since thebase portion of this hanger extends substantially the full height of theflanges 72 of each bracket, said hanger is very stably support upon thecrossarm.

Various and numerous modifications and variations in the construction ofthe nonlineal crossarm for bracketing electrical devices as shown inthis invention, within the scope of the appended claims, will occur tothose skilled in the art in the light of the foregoing disclosure. Thepreferred embodiment, and the variations in the brackets, are merelyillustrative.
